longer life, which increased life permits marked economies in replacement of these parts. As a result of extensive operative tests of the improvements herein described, the blocks 'of theV present vinvention have -an expected operative life of eighteen to twenty-four months, or longer, Which is in marked contrast to that previously obtainable with such devices. c

Referring new to Fig. 4, there is shown. a flier block 13,` Comprising nested threaded members, 14, andk 15, the member being adapted to support the flier wire, which is locked in operative position by the member 14, The bushinglfi, is shouldered to fit the cap 14, and is adapted to slidably t the base member 15.

The construction shown in Fig, 5 comprises a flier block having the cooperating members 14 and'15, as above Ydescribed/andbeing provided' with a band spring adapted to frictionallyengage theV spindle 2. TheV flier block assembly is retained on .the spindle by the cooperation of the spring member and the improvedbushing cpmprisingan upper portion .21 and a lower por-A tion 22 adapted to tinto the vapertures 2:3; 24,.

By :using two such nwmbers it vwill loe-'seen that a .pluraiityof members ofuniform sizeand construct-ion may ibo prepared and replacement may be readily made without requiring a .specialfitting for anygven part of the bushing.

It will beinoted that in` this construction it will not`-be necessary-tp use the specialv flange spring above fdisciosed and` thatv the or.dinar y band spring Y2t may be used.

' The -construction shown in Fig. 7..;involvsfthe use of a bipartite block having a male fmember 15 and afemale cap member `14 4provided with theV usualseeuring means such as 'screw threads, the two partsY being adapted to hold ya flier Wire 6 in operative position.
